OSTI ID:6994028
The interaction of a dense n approx 10/sup 12//cc, mildly relativistic (1.8 < gamma < 3) electron beam and a cylindrical, dielectric-lined waveguide produced tunable microwave radiation in the 150-310 GHZ frequency range with an estimated power output of 500 kW at 150 GHz and 10 kW at 310 GHz. The measured output frequency agrees well with the frequency for which the phase velocity of the TM/sub 1/ mode of the dielectric-lined guide is synchronous with the electron-beam velocity.
